What It Is and How It Works
Ivermectin is an antiparasitic medication. It works by binding to certain proteins in the parasite cells, leading to increased permeability of the cell membrane and ultimately causing paralysis and death of the parasites. This action helps clear the parasitic infection from the host body.
Indications / Uses
Ivermectin is primarily approved for treating specific parasitic infections such as:
- Onchocerciasis: Also known as river blindness, caused by the parasite Onchocerca volvulus.
- Strongyloidiasis: An infection caused by the roundworm Strongyloides stercoralis.
- Head lice and scabies: Sometimes used in topical form to treat these skin conditions.
Off-label uses may include other parasitic infections, but these applications should be under the guidance of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, primarily as oral tablets and topical formulations. The dosing of ivermectin varies based on the condition being treated, the patient’s weight, age, and other health considerations.
